Machine / Crosspoint Numbers
The user interface of an edit controller is the Edit Decision List (EDL). The EDL
allows the user to define edits by specifying a machine or crosspoint number, edit
point, type of edit, and transition time. The EDL is where edits are entered and edited,
and then executed.
Machines (such as VTR’s) are given numbers to identify them in the EDL. This
number is called the Machine Number or Crosspoint Number.
The editing system uses these Machine Numbers to assign the DAFV
2
inputs to
Program and or Preset Buses.
These Machine Numbers should be entered on a “hardware” menu in the Editing System.
An EDL command to “Dissolve from Machine 1 to Machine 2” puts Machine 1 (VTR
A) on the Program Bus and Machine 2 (VTR B) on the Preset Bus.
When an edit controller sends a command to assign Machine 0 to a Bus, this results in
the Bus Assignments turning off.
For example, a command to put Machine 0 onto Preset Bus would turn off everything
on the Preset Bus.
Procedures for Edit Controlled Cut
• Check that you have followed the procedures for preparing for a session, specifically,
that all interconnections have been made and levels are set.
• Ensure that the edit controller is communicating with DAFV
2
.
• On the edit controller, set up a cut by marking Source VTR and Record VTR in and
out edit points. On the edit controller, program the mode of the audio edit, A1, A2, or
both. That is to say, set up the Record VTR to record on track 1, track 2, or both.
• Select the desired input source(s) on the DAFV
2
Program Bus.
Select by entering machine / crosspoint numbers and destination bus on the edit
controller.
